The pictures that I use to express my feelings, are part of a Harry/Draco moodtheme, which was assembled by shaggirl and it includes art from a large number of different artists, here you can see a list of al the pics with the name of the artist (http://www.livejournal.com/users/shaggirl/86071.html)

As for my icon? Which ones do you mean? Some are also Harry Potter fanart, this one is a model, if you go to my userinfo and click on the avatar there you will see all the other ones and who made them.

Hope that was of help. :)
